This allows you to check oil pressure in automatic transmissions and gasoline engines. Also test all Domestic cars and light trucks and most Imported cars and light trucks. This is more accurate than dashboard oil pressure gauges. It's especially helpful on cars with dash indicator lights only. This set includes two gauges, a large gauge that is for all applications and a small gauge that is for more accurate readings of lower engine oil pressures. This set is included in a plastic case with instructions.
